Riparian Revegetation
The process of rehabilitating creeklines to stabilise streambanks and provide habitat for fauna:
- creek line emphoral
- gully rehabilitation
- weeding
- sandstone capping
- planting and /or direct seeding
- plant sourcing
- seed collection
- contract growing
- channel armouring
- plant transplants
Riparian vegetation is made up of the native plant species that grow alongside acreeklines, enhancing the habitat value of an area and providing stability to creek banks.
Riparian revegetation can halt the degradation of land alongside waterways, prevent erosion of creek banks during storm events and provide habitat for fauna.
channel armouring
Revegetation is carried out via a variety of techniques depending on the resilience and health of the site and the reason for the revegetation.:
Natural regeneration occurs when an area is fenced off from traffic (pedestrian or large animals) and a weed management regime is undertaken to allow the local seed bank to regenerate naturally.
Planting or Direct Seeding can occur if the site is so degraded that the seed bank has been exhausted and artificial intervention is necessary.
Using locally sourced endemic seed and tubestock, an area can be assisted in its regeneration. An understanding of the positioning of species along the creek bank is important to replicate the natural environment and provide stability in the soil.
Some species play a role closer to the edge of the stream slowing down the flow of the water and stabilising the bank whilst other species positioned at the top of the riverbank assist to bind the soils together with their deep root penetration. Studying other areas of a creekline that is still in a natural state can assist in the selection of species.
We can advise and select appropriate species for your project and can assist with the collection and contract growing of your particular locally endemic species.
Waratah Eco Works often fabricates creeklines where they informally have been created at the end of stormwater pipes usually toward the end of streets where they discharge into bushland.
Waratah Eco Works makes sediment and velocity control devices which also provide aquatic habitat for various critters.
